To all whom it may concern:

Be it known that T, GEORGE E. HANEY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Locks, of which the following is a specification.

My invention relates to improvements in looks, in which a dial is turned to a certain position to open the lock; and the objects of my improvements are, first, to provide a grooved disk inside of the lock; second, to provide a groove on the inner surface of the dial crossing the grooves on the inner disk; third, to provide operating means, as a steel-ball, or the like, between the dial and the inner disk to slide or roll in the grooves to a certain stop, at which the lock can be opened; fourth, to provide a lock which can be opened when held in a certain position only, as horizontally, vertically, sidewise, or any desired position; fifth, in padlocks, to provide a stop which requires a certain pressure against the bow to. open the lock; and, sixth, to provide a lock which operates absolutely noiseless, while in other safety-locks a number of springs will give a chance for an expert to find or listen to the difierent operations in the lock, in my lock the ball is simply rolling around the grooves without any pressure, therefore my lock can be opened by a person who knows the secret of that certain look only. The invention consisting in the combination, construction and arrangement of devices hereafter more fully described and claimed, and illustrated in the accompanying drawing, in which Figure 1 is my device applied to a padlock, which is shown in horizontal section. Fig. 2 is the same in cross section. Fig. 3 is the inside view of my dial, showing the cross groove. Fig. 4 is my grooved inner disk, in top View. Fig. 5 is a spring of round steel, brass, or a suitable material.

Similar numbers refer to similar parts throughout the several views.

Showing my device applied to a padlock, see Fig. 1, constituted by the casing 1 and the how 2, I insert my grooved disk 3 therein. The grooved disk 3 is provided with a lug 4, which projects between a spring 5 and the lOWer end of the how 2. A locking stop 6 is provided on the grooved disk 3 at a suitable distance above the lug 4, and an escape preventing stop 7 is provided a suitable distance above the locking stop 6. Near the lower end 8 of the how 2, I prefer to cut a circular recess 9, normally engaging the locking stop 6 of the grooved disk 3. A groove 10 is cut longitudinally in the bow 2. On the surface of the grooved disk 3, T provide a combination of grooves, which will vary in different looks. A ball 11 placed in the grooves of the disk 3, shown in Fig. 1, will come back to the same point when pushed in either direction. Pushing the ball 11 in the right hand direction, it will pass the junction 12 and roll farther back to the same point where it is shown. Pushing the ball 11 to the left hand, it will follow the straighter course past the junction 12, passing the junction 13 and 14: back to the same point where it is shown. But, pushing the ball 11 past the junction 12 in a left hand direction, and changing the turning or pushing direction as soon as the ball 11 passes the junction 13 in a right hand direction, or at least before the ball comes to pass the junction 14:, the ball will, by turning in right hand direction, roll to the end 15 of the grooves, which will be the turning point of my grooved disk 3. And as the junctions in my grooves can be made in a great variation, it will be hard for a person who is not acquainted with the secret of a certain lock to open the same.

The disk 3 in the lock casing 1 is covered as shown in Fig. 2 by a dial 16. The dial 16 is turna-bly mounted in a recess 17 of the casing 1. The extension 18 of the dial 16 extending downwardly into the look as well as the recess 17 in the casing 1 are provided with a groove 22 for the spring 19. The part of the groove 22, cut into the extension 18 of the dial is deep enough to take up the full thickness of the spring 19.

Pressing the spring 19 into the groove 22 of the dial, the dial with the spring 19 can be inserted into the recess 17 of the casing 1. As soon as inserted into the casing 1, the spring 19 will expand and fill out with its outer half the groove 17 of the casing and will remain with its inner half in the part of the groove 22 in the dial, thus closing the lock that it can hardly be opened, and no other person can operate the lock except who bought it with the instruction for that certain lock. On the inside surface, the dial is provided with a groove 20, see Figs. 2 and 3, which, when placed above the disk 3, will cross the grooves in the disk 3.

'Having my dial 16 placed into its position in the lock, it will be understood that the ball 11 is rolling between the dial 16 and the disk 3, asshown in Fig. 2. Turning then my dial in a right hand direction, it will be understood from the previous description that the dial will never come to a stop, but, coming with my dial to a position to bring the inserted ball past the junction 12, I change the direction and turning to the left hand, I come to the junction 13, where again I change the direction and turning to the righthand come to the stop 15. It will easily be understood that outside of the casing and on the dial, any number of graduations can be had, by which the junction inside of the lock may be known and found, by turning the dial.

In a padlock as shown on my drawing, it will be advisable to keep the lock in a horizontal position, as the grooves as shown in this case are made so that the ball 11 would roll back to the old point after it had passed the junction 13 when held in a vertical position instead of going up to the end 15. This is one of my improvements, that the lock can be operated only when held in a certain position for which it was designed.

In padlocks, I prefer to make the spring 5 so strong that it would not be possible to open the look by the dial alone, but requiring a push against the bow 2, by which the grooved disk 3 is turned, as the end 8 of the bow 2 is resting on the lug 41 of the disk 3. Turning thus the disk 3, the lock ing stop 6 disengages from the circular recess 9 of the bow end 8, after which the bow may be pulled out of its locked position. Pulling the bow 2 out of the lock, the escape preventing stop 7 slides along the grooves 10 until it comesto the circular recess 9. Pulled out'that far, the bow 2 can be turned to be removed from the hasp or wherever the lock is used, as the escape preventing stop 7 is sliding around the bow end 8 in the circular recess 9, and the bow cannot be pushed in and the look not closed, except when the bow is turned in the correct position. The escape preventing stop 7 is resting against the shoulder 21 of the lock casmg 1, preventing at the same time the grooved disk 3 from turning further.

Having described my device applied to a padlock, it will easily be understood that this device can just as well be used in any other lock.

Having thus described my invention, I claim:

1. A look comprising a casing, a dial, a grooved disk, a ball placed between the dial and disk engaging the dial and the disk, and a locking member engaging with the disk.

2. A lock of the type described having a casing, a dial turnably mounted in the casing having a groove in the inner surface radially positioned, a disk concentrically below the dial turnably mounted and having a combination of grooves joining at cer tain points, a ball inserted between the dial and the disk adapted to be moved by the dial along the combination grooves in the disk to a stopping point engaging the disk and the dial, and a locking member engaging with the disk.

3. A lock of the type described, consisting of a casing having a chamber therein, a disk turnably mounted in the chamber of said casing having a combination of grooves provided in the upper surface, a locking stop formed at a suitable place on the disk, a corresponding member inserted into the casing adapted to engage with the locking stop of the disk, a dial turnably mounted concentrically above the disk and closing the chamber of the casing, a groove formed radially on the inner surface of the dial, and a ball placed between the disk and the dial designed to fit in the combination grooves of the disk and the radially positioned groove in the dial adapted to be operated by the dial to disengage said locking stop and said member.

4. A look of the type described, consisting of a casing having a chamber therein, a disk turnably mounted in the chamber of said casing, a combination of grooves formed in the upper surface of the disk being joined so as to form a single stopping end, a locking stop formed at a suitable place on the disk, a corresponding member inserted into the casing having a circular recess near the innermost end adapted to engage with the locking stop of the disk, a dial turnably mounted concentrically above the disk and closing the chamber of the casing, a groove formed radially in the in ner surface of the dial, a groove formed longitudinally in the inserted end of said member adapted to prevent the closing of the lock except when turned into the correct position, and a ball placed between the disk and the dial designed to fit in the combination grooves of the disk and the radially po.

sitioned groove in the dial, said combination grooves formed to allow the ball to roll in the desired direction when holding the lock in a certain position only.

5. A look of the type described, consisting of a casing, a disk turnably mounted in the casing, a combination of grooves formed stop,' a dial turnably mounted above the disk and closing the casing, a groove formed radially in the inner surface of the dial, a ball placed between the disk and the dial fitting in the grooves, and a spring placed against a suitable part of the disk adapted 10 to require a push against the inserted memher to open the lock.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.
